Learning guidePrivacyInstructorSolo game

Same market. Equal starting cash. Your own decisions.

Join a game

Enter a room code and choose a nickname. No email account needed.

Choose a color-and-animal name. Use this name to identify yourself to your teacher or friends.
Returning with a private rejoin code?Enter your room code above and paste your private code here to restore your portfolio. You do not need to select your old nickname.

Create a game

Play head-to-head, invite a group, or host a class. Up to 40 players trade the same fictional stocks. Highest percentage return wins.

Education mode - Educator accounts create rooms. Students join by code. The approved fictional market is shared by all players.

Customize pace, duration, cash and stock pool

Move right for faster activity. Timed games keep their selected length. Stocks move independently.

A challenge creates a two-player timed game. Share its invite link after creating it.

Your room

Keep your private link to yourself. It opens your existing portfolio. Teachers can sign into their instructor account on another device.

The host controls the clock for everyone. Refreshing or closing a window does not pause the game. Return in the same browser, or use your private continuation link on another device.

To continue another day, the host chooses Pause and continue later. Wait for the saved confirmation before closing. Students return in their remembered browser or use their private continuation link; the teacher signs in and presses Resume game when the class is ready. Keep browser data to retain access. After choosing Leave room, enter the room code again in this browser to return.

Before your next trade: what is your best alternative, and what risk are you taking?

Extend game time

Add time for everyone without resetting prices, portfolios, or lesson questions. Continuous markets have no time limit.

Save your private rejoin code

Saved for another day

The clock, prices, portfolios, and pending orders are saved subject to the storage deadline shown in Room menu. Everyone can close the game now. Return in your remembered browser or use your saved access. The host resumes when everyone is ready.

Your classroom is saved on the server. Clearing browser site data removes remembered access, not the saved game. Teachers can sign back in to Instructor. Students can use their private rejoin code or ask their teacher for it under Room menu > Student rejoin codes. A room invitation alone does not identify your portfolio.

Save session template

Copies settings and lesson questions only. Players, answers, trades, and school declarations stay with this room.
